Description
Technical Field
The embodiment of the invention relates to the technical field of wind power, in particular to a monitoring method and a monitoring system for a wind vane of a wind generating set and the wind generating set.
Background
With the gradual depletion of energy sources such as coal and petroleum, human beings increasingly pay more attention to the utilization of renewable energy sources. Wind energy is increasingly gaining attention as a clean renewable energy source in all countries of the world. The wind power generation device is very suitable for and can be used for generating electricity by utilizing wind power according to local conditions in coastal islands, grassland pasturing areas, mountain areas and plateau areas with water shortage, fuel shortage and inconvenient traffic. Wind power generation refers to converting kinetic energy of wind into electric energy by using a wind generating set.
The wind vane is an important component of the wind generating set, and has the main functions of measuring the real-time wind direction as a basis for yawing, reducing the load of the wind generating set and realizing the maximum wind energy capture of the wind generating set. At present, with the capacity of a wind generating set increasing, blades are also longer and longer, the load and power loss influence caused by yaw errors is more and more obvious, and the effectiveness of a wind vane is more and more important.
At present, wind speed and wind direction measurement of a wind generating set has a mechanical type and an ultrasonic type traditional measurement method, and also has feedforward measurement tools such as a laser anemometer and the like. In view of economy and functionality, a general wind generating set uses two mechanical and ultrasonic wind vanes to measure wind direction at present, and the two wind vanes are redundant with each other.
The effectiveness measurement of the current wind vane mainly depends on the mutual comparison between two wind vanes, and when the data of the two wind vanes are inconsistent, the wind vane continues to operate by taking the value with high value as the standard or taking the average value; and some manufacturers can directly report the fault shutdown when the data is inconsistent. However, in the mechanical and ultrasonic wind vane combination, when one or two wind vanes fail, the fed back data are inconsistent, and it cannot be accurately judged which specific wind vane fails through the data, and it is unreasonable to judge by the size of the data alone, and the validity of the wind vanes cannot be accurately reflected. And if the two data are inconsistent, the direct shutdown is carried out, and the loss of the power generation amount of the fan is also caused.

Fig. 1 discloses a schematic side view of a wind park 100 according to an embodiment of the invention. As shown in FIG. 1, wind turbine generator system 100 includes a tower 101, a nacelle 102 mounted on top of tower 101, a hub 103 mounted at one end of nacelle 102, and a plurality of blades 104 mounted on hub 103. The wind generating set 100 of the embodiment of the present invention further includes a wind vane monitoring system 200 (shown in fig. 2) of the wind generating set 100, which is used for monitoring the effectiveness of the wind vane of the wind generating set 100.
Fig. 2 discloses a schematic block diagram of a system 200 for monitoring a wind vane of the wind park 100 according to an embodiment of the invention. As shown in fig. 2 with reference to fig. 1, a monitoring system 200 of a wind vane of a wind turbine generator system 100 according to an embodiment of the present invention includes a first wind vane 201, a second wind vane 202, an anemometer 203, a torque sensor 204, and a controller 210 installed on the wind turbine generator system 100. The first wind vane 201 may comprise, for example, a mechanical wind vane and the second wind vane 202 may comprise an ultrasonic wind vane. The first wind vane 201, the second wind vane 202 and the anemometer 203 are mounted on the nacelle of the wind park 100. Torque sensor 204 is mounted on top of tower 101 of wind turbine generator system 100. As shown in the enlarged view of the dashed circle portion in fig. 1, the torque sensor 204 will deform without wind. FIG. 3 discloses a torque diagram of tower 101 of wind turbine generator system 100 shown in FIG. 1 when a wind direction deviation exists. Referring to fig. 3, when there is a wind direction deviation, the tower 101 will generate a certain torque M, and the torque information of the tower 101 can be measured by the torque sensor 204 disposed at the top of the tower 101.
With continued reference to fig. 1 and 2, controller 210 may be disposed, for example, at the bottom of tower 101. The controller 210 may include a data acquisition module 211, wherein the first wind vane 201, the second wind vane 202, the anemometer 203, and the torque sensor 204 are each connected to the data acquisition module 211. During operation of the wind turbine 100, the data collection module 211 may collect signals from the first wind vane 201, the second wind vane 202, the anemometer 203, and the torque sensor 204, respectively. The controller 210 may obtain a first wind direction measurement WD1 of the first wind vane 201, a second wind direction measurement WD2 of the second wind vane 202, a wind speed measurement W of the anemometer 203, and a torque measurement T of the torque sensor 204, respectively, through the data acquisition module 211. The data collection module 211 may perform data processing, such as analog-to-digital conversion, on the collected signals of the first wind vane 201, the second wind vane 202, the anemometer 203, and the torque sensor 204, so as to obtain a first wind direction measurement value WD1, a second wind direction measurement value WD2, a wind speed measurement value W, and a torque measurement value T, respectively.
When the wind generating set model is simulated in a Bladed load simulation software, yaw torque values under different wind conditions can be counted, and the yaw torque values are related to blade wing profiles, the center distance of a wind turbine tower, wind speed values, wind direction deviation values and the like. Since the yaw torque is transmitted to the tower to be substantially consistent with the tower wall torque measurement, and other relevant parameters are fixed values of the wind generating set model, the tower wall torque is relevant to the wind speed and the wind direction. Therefore, the controller 210 may calculate the equivalent wind direction value WD0 based on the wind speed measurement W and the torque measurement T. In some embodiments, the relationship between wind speed and wind direction and torque may be fitted in advance through simulation data and stored in the controller 210, and the controller 210 may calculate the equivalent wind direction value WD0 based on the actual wind speed measurement value W and the torque measurement value T and according to the relationship between wind speed and wind direction and torque obtained through fitting in advance. In other embodiments, a two-dimensional table of wind speed, wind direction and torque may be obtained in advance through statistical data and stored in the controller 210, where the horizontal direction is the wind speed and the vertical direction is the wind direction, and the torque value is filled in the table of the two-dimensional table, and the controller may obtain the actual wind speed measurement value W and the equivalent wind direction value WD0 corresponding to the torque measurement value T through a table lookup method. After calculating the equivalent wind direction value WD0, the controller 210 may further monitor the effectiveness of the first and second wind vanes 201, 202 based on the first and second wind direction measurements WD1, WD2, and the equivalent wind direction value WD 0.
The wind vane monitoring system 200 of the wind generating set 100 of the embodiment of the invention fully considers the power generation requirement of the wind generating set 100, checks the validity of wind vane data measurement by additionally arranging the torque sensor 204 and connecting signals into the controller 210 and utilizing the obtained real-time wind speed measurement value W and the torque measurement value T to reversely push the equivalent wind direction value WD0, thereby avoiding the potential safety hazard of the wind generating set 100 caused by misjudgment of the wind vane fault and avoiding the loss of the power generation amount of the wind generating set 100 caused by direct shutdown.
The wind generating set 100 with the monitoring system 200 of the embodiment of the invention can monitor the effectiveness of the wind vane in real time in the operation process, can improve the monitoring accuracy of the wind vane, avoids potential safety hazards caused by misjudgment of the fault of the wind vane, and can also avoid power generation loss caused by direct shutdown.
Fig. 4 discloses a schematic block diagram of the controller 210 according to an embodiment of the present invention. As shown in fig. 4, in some embodiments, the controller 210 may further include a logical operator 212, a first comparator 213, and a second comparator 214. During normal operation of the wind park 100, the controller 210 may use the corresponding first wind direction measurement WD1 of the first wind vane 201 and/or the second wind direction measurement WD2 of the second wind vane 202 as a basis for control according to different wind conditions. When the first wind direction measurement value WD1 of the first wind vane 201 and the second wind direction measurement value WD2 of the second wind vane 202 acquired by the controller 210 through the data acquisition module 211 deviate, for example, when the first wind direction measurement value WD1 and the second wind direction measurement value WD2 are greatly different or abnormal, the controller 210 may obtain a real-time wind speed measurement value W and a real-time torque measurement value T through the data acquisition module 211, and the logic operator 212 of the controller 210 may calculate the equivalent wind direction value WD0 in real time according to the obtained real-time wind speed measurement value W and the obtained torque measurement value T. The first comparator 213 of the controller 210 may compare the first wind direction measurement WD1 with the equivalent wind direction value WD0, for example, the first comparator 213 may calculate (WD1-WD0)/WD0, resulting in a comparison result R1. The second comparator 214 of the controller 210 may compare the second wind direction measurement WD2 with the equivalent wind direction value WD0, for example, the second comparator 214 may calculate (WD2-WD0)/WD0, resulting in a comparison result R2.
The controller 210 may monitor the effectiveness of the first vane 201 based on the comparison R1 of the first wind direction measurement WD1 and the equivalent wind direction value WD 0. Fig. 5 discloses a schematic diagram of determining the effectiveness of the measurement of the first wind vane 201 based on the comparison result R1 between the first wind direction measurement value WD1 and the equivalent wind direction value WD0 obtained in fig. 4. As shown in fig. 5, the controller 210 determines whether it exceeds a predetermined limit ERRValue according to the comparison result R1 between the first wind direction measurement value WD1 and the equivalent wind direction value WD 0? If the comparison result R1 between the first wind direction measurement value WD1 and the equivalent wind direction value WD0 exceeds the predetermined limit value ervveraue, it is determined that the first wind vane 201 is abnormal, that is, the first wind vane 201 fails; if the comparison result R1 between the first wind direction measurement value WD1 and the equivalent wind direction value WD0 does not exceed the predetermined limit ervalue, the first wind vane 201 is determined to be normal, i.e., the first wind vane 201 is valid.
Likewise, the controller 210 may monitor the effectiveness of the second wind vane 202 based on the comparison R2 of the second wind direction measurement WD2 and the equivalent wind direction value WD 0. Fig. 6 is a schematic diagram illustrating the determination of the measurement validity of the second wind vane 202 based on the comparison result R2 between the second wind direction measurement value WD2 and the equivalent wind direction value WD0 obtained in fig. 4. As shown in fig. 6, the controller 210 determines whether it exceeds the predetermined limit ervroad based on the comparison result R2 between the second wind direction measurement value WD2 and the equivalent wind direction value WD 0? If the comparison result R2 between the second wind direction measurement value WD2 and the equivalent wind direction value WD0 exceeds the predetermined limit value ervveraue, it is determined that the second wind vane 202 is abnormal, i.e., the second wind vane 202 fails; if the comparison result R2 between the second wind direction measurement value WD2 and the equivalent wind direction value WD0 does not exceed the predetermined limit ervalue, the second wind indicator 202 is determined to be normal, i.e., the second wind indicator 202 is valid.
Fig. 7 discloses a schematic view of the operation judgment of the wind turbine generator system 100 according to an embodiment of the present invention. As shown in FIG. 7, in some embodiments, the controller 210 may further include an OR gate 215, and the OR gate 215 may perform an OR determination based on the normality of the first wind vane 201 and the second wind vane 202. The logical OR circuit 215 receives the logical inputs of the first vane 201 and the second vane 202, whether normal or not, and generates a logical output. When the first vane 201 is normal, the logic input is 1; otherwise, the logic input is 0. Similarly, when the second vane 202 is normal, the logic input is also 1; otherwise, the logic input is 0. Thus, when at least one of the first wind vane 201 and the second wind vane 202 is normal, then the logic outputs are both 1. When both the first wind vane 201 and the second wind vane 202 fail, then the logical output is 0. The controller 210 may further determine whether the result is true based on the logic output of the or gate 215. When the logic output is 1, the judgment result is true; when the logic output is 0, the determination result is false. When the determination result is true, that is, when at least one of the first wind vane 201 and the second wind vane 202 is determined to be not failed, the controller 210 may control the wind turbine generator set 100 to continue normal operation based on the wind vane that is not failed. When the determination result is false, that is, when both the first wind vane 201 and the second wind vane 202 are determined to be failed, the controller 210 may control the wind turbine generator system 100 to stop.
The system 200 for monitoring the wind vane of the wind generating set 100 according to the embodiment of the invention can monitor whether the wind vane fails in real time in the operation process of the wind generating set 100, and can use the wind vane which does not fail as a control basis, so that the generated energy can be ensured under the condition of ensuring the safety of the wind generating set 100.
The embodiment of the invention also provides a method for monitoring the wind vane of the wind generating set 100. Fig. 8 discloses a flow chart of a method for monitoring a wind vane of the wind turbine generator system 100 according to an embodiment of the invention. As shown in fig. 8, the method for monitoring the wind vane of the wind turbine generator set 100 according to the embodiment of the present invention may include steps S11 to S14.
In step S11, a first wind direction measurement WD1 of a first wind vane 201 and a second wind direction measurement WD2 of a second wind vane 202 installed in the wind turbine generator set 100 are acquired, respectively. The first wind vane 201 may comprise, for example, a mechanical wind vane and the second wind vane 202 may comprise an ultrasonic wind vane.
In step S12, a wind speed measurement W and a torque measurement T of the tower of the wind turbine are obtained.
Alternatively, when a deviation occurs between the first wind direction measurement WD1 and the second wind direction measurement WD2 acquired in step S11, the process may proceed to the step of acquiring the wind speed measurement W and the torque measurement T in step S12.
In step S13, the equivalent wind direction value WD0 is calculated based on the wind speed measurement value W and the torque measurement value T acquired in step S12.
In step S14, the validity of the first and second wind vanes 201, 202 is monitored based on the first and second wind direction measurements WD1, WD2 and the equivalent wind direction value WD0 calculated in step S13.
In some embodiments, monitoring the validity of the first vane 201 and the second vane 202 based on the first wind direction measurement WD1, the second wind direction measurement WD2, and the equivalent wind direction value WD0 of step S14 may include: monitoring the effectiveness of the first wind vane 201 based on the comparison R1 of the first wind direction measurement WD1 with the equivalent wind direction value WD 0; and monitoring the effectiveness of the second wind vane 202 based on the comparison R2 of the second wind direction measurement WD2 and the equivalent wind direction value WD 0.
When the comparison result R1 of the first wind direction measurement value WD1 and the equivalent wind direction value WD0 exceeds the predetermined limit ERRValue, judging that the first wind vane 201 is failed; when the comparison result R1 between the first wind direction measurement value WD1 and the equivalent wind direction value WD0 does not exceed the predetermined limit ervalue, the first wind indicator 201 is determined to be valid.
When the comparison result R2 of the second wind direction measurement value WD2 and the equivalent wind direction value WD0 exceeds the predetermined limit ERRValue, judging that the second wind vane 202 is invalid; when the comparison result R2 between the second wind direction measurement WD2 and the equivalent wind direction measurement WD0 does not exceed the predetermined limit ervalue, the second wind indicator 202 is determined to be valid.
In some embodiments, the method for monitoring the wind vane of the wind turbine generator set 100 according to the embodiment of the present invention may further include: when at least one of the first wind vane 201 and the second wind vane 202 is determined not to be failed, controlling the wind generating set 100 to continue to operate based on the wind vane which is not failed; and when the first wind vane 201 and the second wind vane 202 are judged to be invalid, controlling the wind generating set 100 to stop.
